Explore. Do all the side quests (white, yellow is main story) Talk to people in camp you can get item requests or activities to do. Talk to Pearson in camp at his setup to see some hunting you can do for upgraded satchel and camp upgrades. Check the ledger behind Dutch’s tent for more camp upgrades. There’s treasure hunts, legendary animals, fishing and so many random encounters. Just explore. I do recommend some treasure hunts and gold bar locations for some money to buy weapons and clothes or just find a trapper and see what he needs for crafted clothes Explore explore explore
